The attacker can then use these 1000 computers to simultaneously attack websites and take them down. Suppose the trojan spread to 1000 computers (a very small number, there are HUGE botnets out there). They are often used to carry out DDOS attacks. Botnet is basically a large network of infected computers which the attacker uses to do his bidding.
